Experimental factsWhen light waves are shed onto a photoelectric material, and in specific conditions, a current of electrons is emitted out of the surface of the material.IntroductionThe graphs below represent a photoelectric material, on which light, represented by the sinusoidal curve is shed.The characteristics of light are two:
The speed of the electrons is represented with arrows going through the letter e. The faster the electron the longer the arrow. The slower the electron the shorter the arrow. In physics the speed of an electron is also its energy. The role of the Wave FrequencyExperimentations show that electrons extraction is exclusively dependent on the wave's frequency of the light hitting the photoelectric material.In short there is a frequency treshold below which no electrons are extracted and frequencies above which electrons are extracted. The frequencies appearing on this web page have all been chosen above the frequency treshold of the photoelectric material represented.
Furthermore the higher the frequency of the wave (the bluer) the higher the energy (the speed) of the electrons emitted. Obviously the electrons within the material are induced to move back and forth as a yoyo, along the light frequency's peaks and troughs. An electron encountering the wave starts wobbling on a small scale, it then gets momentum and its back and forth motion takes more and more amplitude until ejected. The higher the frequency the faster the electrons' oscillating motion within the material, and the faster they escape, or the higher their emitted speed. On this graph the light frequency is higher than on the next and the energy of the electrons emitted, or their speeds, which is represented by the length of the arrows, is higher than on the next graph.
The lower the frequency of the wave (the redder) the slower the oscillating motion of the electrons within the material and the lower the speed (the motion) of the electrons emitted.On this graph the light frequency is lower and the electrons energies (their speeds) representation follow suit, the arrows are shorter. Decrease further the frequency and the electrons barely make it out.
Both Light Frequency and Light Intensity carry EnergyThe gravimotion mechanism Click and get this book! On the other hand when the wave frequency is above the treshold, increasing the intensity of the wave will increase the number of electrons, yet not their speed. The role of the Wave Intensity
When electrons are emitted (when the frequency permits) the higher the intensity of the light wave the higher the number of electrons emitted.The light frequency on this graph is the same as the one in the graph just above. Yet the peak to peak amplitude of the wave (the light's brightness in the real world) is much higher. As can be seen increasing the light intensity increases the number of electrons emitted but not their energy; their speed or motion remains the same. In other words when electrons are emitted, increasing the intensity increases the number of electrons but not their individual energy (not their motion). And when electrons are emitted, if the light intensity doesn't change, no matter the frequency, the same number of electrons are emitted. See graphs 1 and 2. Eisntein's interpretationSince electrons "particles" are dislodged, Einstein declared that "particles" (likened to "packets of energy") had to knock them off!Einstein theorized that light is made of packets of energy and that these "light particles" when colliding with electrons provide the later enough speed energy as to overcome the surface barrier of the photoelectric material. Because in "reality", or because the experiments show that the wave's frequency is the cause of emission, Einstein's particle, which has been called the photon since, is "mathematically" made of "frequency". These "frequency" type particles, as any material particle would, allegedly impact mechanically the mass of the electrons and throw the later in motion. Physics' photon acts as if it were made of mass, yet that very photon has no mass in physics! Worse, and most surprisingly, that photon has no electromagnetic characteristic either! Having no mass and being electrically neutral, the question is then: what is the fabric of the photon? The photon has an incredible if not lethal "physical handicap"! Obviously the nature of the photon is mathematical and not physical! The photon is fictitious (a mathematical idea) and has no particle-like colateral in reality. Nevertheless, since then in physics light waves travel in vacuum and transport their energy, through photons so called particles; particles that are made of nothing, particles that have no mass and no electric charge! Gravimotion's interpretationInduced by the wave, the oscillating motion of the electrons within the photoelectric material (gravimotion's interpretation), is pure elegance!As a matter of fact, by comparison, the incongruity of the photon spoils human's interpretation of Nature. Light's very electromagnetic oscillating field, acting directly on the electron's own surrounding electrical field, induces the later into a back and forth motion increasing incrementally as to permit extraction; that is simple to understand and logical. It makes sense! Once a professional physicist asked me the question: What do you mean by it makes sense? Well! This web page explains what I mean by it makes sense. To me physics' wave particle duality doesn't make sense, while the above simple and evident interpretation makes sense!
